Gas Turbine Plant

Abstract

A gas turbine plant, wherein a first gas turbine positioned coaxially with a compressor and a second gas turbine positioned coaxially with a generator are rotated by a coolant heated by heat energy provided by the fission of a coated particle fuel. The rotational speed of the first gas turbine is controlled by controlling a flow in the bypass passage of the second gas turbine.
